What Would a Large Earthquake Do to Downtown L.A.?
From the USGS Newsroom:
USGS scientist Ken Hudnut fills us in on how science created the theoretical magnitude 7.8 earthquake behind the Great Southern California ShakeOut—the largest earthquake preparedness drill in U.S. history, coming Nov. 13—and what such an earthquake would do to downtown Los Angeles.
Seems like they did it right wiith this study. They had multiple teams independenlty come up with the ground shaking model, then had different structural engineers who are experts in seismic design of large buildings review the tall buildings in the L.A. area for the design earthquake. They say that buildings would likely come down in the 7.8 magnitude event. Click through to watch the video interview from the USGS.

New FHWA Mechanically Stabilized Earth Retaining Wall (MSE Wall) Manual
The much anticipated LRFD update to the MSE Wall and Reinforced Soil Slope Manual is now available for download from the FHWA’s website. The full title of the document is Design of Mechanically Stabilized Earth Walls and Reinforced Soil Slopes and it was authored by Ryan R. Berg, P.E.; Barry R. Christopher, Ph.D., P.E. and Naresh C. Samtani, Ph.D., P.E. Find the abstract and download link below. As time permits, I’ll try to post more about some of the changes in this important geotechnical publication.
